Vol. XI] VAN DENBURGH-SLEVIN— AMPHIBIANS AND REPTILES 61 



Average 29. The femoral pores in forty-four specimens ex- 

 amined vary from sixteen to twenty-two ; being 16 five times, 

 17 twenty-six times, 18 seventeen times, 19 seventeen times, 

 20 ten times, 21 twelve times, and twenty-two once; the average 

 in eighty-eight thighs being 18.46. 



36. Sceloporus orcutti Stejneger 



Two specimens (Nos. 3791, 3840) secured at San Xavier are 

 of interest as confirming our belief that Mocquard's S. digueti 

 is based upon this species. 



37. Sceloporus licki Van Denburgh 



This, the smaller of the two Scelopori found in the Cape 

 Region, was collected at San Antonio, Todos Santos, Guamu- 

 chil Rancho, Cabo San Lucas, San Jose del Cabo, Miraflores, 

 Agua Caliente, San Bartolo, Triunfo, and La Paz. The species 

 was found to range from sea-level to 1172 feet at Miraflores. 

 It generally is found among the rocks in small arroyos and 

 seldom is seen upon the ground. Being extremely shy, it will 

 not allow one to approach nearer than fifteen or twenty feet, 

 when it makes a hasty retreat to some nearby crevice or rock- 

 pile. The males at this time of year (July) were brilliantly 

 marked, and the sun shining on the metallic purple and green 

 scales would at once attract the attention even of a casual 

 observer. 



The female shows none of the brilliant coloring of the male, 

 and at first glance looks not unlike its northern congener, 5. 

 occidentals. A male (C. A. S. No. 46808) was colored 

 in life as follows : A band of metallic purple six scales wide 

 extends from shoulder to base of tail; lateral scales bronze, 

 bordered with black ; scales on belly green bordered with black ; 

 throat black mottled with green; under surfaces of thighs 

 green, and of tail, gray ; a large black patch in front of each 

 fore limb. 



In the specimens collected the femoral pores vary from 13 

 to 18; being 13 four times, 14 seven times, 15 twenty times, 

 16 twenty-six times, 17 sixteen times, and 18 five times. The 

 average in seventy-eight thighs is 15.95.
